SPRING' CUSHION CONSTRUCTION.

Specication'of Letters Patent. Patmtgo'NW/vo p59; 19ML npplicationnlel. January 30,1919. Serial No. 273,957.

4To allfwhomtmay concer/n.

Be ,it known. that I, LoUis A.. Sunxorr, a citizenof the United States, residing at Chicago,'in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sipring Cushion Constructions, of which the specification.

This invention relates to improvements in 4spring cushion constructions adapted for incorporation in seat and mattress structures, and it has for its object to provide a construction of this character wherein maxim-um economy may be effected in the amount of materials employed when producing the con-` struction. I t

Furthermore, the invention also contemplates the provision of a novel form and arrangement of the spring units and their envelope, whereby but al single ply of material is present between contiguous springs,

' thus eliminating unnecessary use of the fabric of the `envelops and at the Sametime providing the requisite separation of the springs to prevent their contact' with each other. The sound of the springs in their relative movement with respect to' each other is thereby precluded, while material saving ering for the springs is effected.

@ther objects and advantages will appear as the nature of the improvements is better understood, the invention cpnsisting substantially in the novel construction, coinbination and' arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, .and finally pointed out in the 'appended claims.

Inthe drawingsy Figure 1 is a top plan view of one form in dotted lines, and likewise theJJ dividing following, is a distance to accommodate the length of a plurality of springs 16. The free ends of this strip are suitably connected together, as at 17, as by stitching, or'any other suitabi@ forvmrof fastening, thereby holding the stripin suchmannerv that the parallel, portions thereofI may be distended under the expansive force of the springs 16. At ,suitable points in the length of the parallel'por-v tions of the strip 15 is arranged a series of division Walls or partitions 18. These partitions 18 are of textile fabric and their ends are fastened to the parallel portions' of the strip 15, as by stitching 19 or itsvequivalent, thereby connecting the walls 18 at spaced intervals and vthus forming a series of pockets or cells for the reception' of the springs 16. The parallel portions of the strips 15 to which the ends of the partitions 18 are connected constitute the tops and bottoms of the several units.

It will be understood that each ofthe strips 15 may be of any desired length to provide the required'size tov be Aincorporated in the particular cushion or mattress structure, and each of these .strips with itsA connected artition walls forms a separate unit which is independent of the other strips. When each of these units is formed in the manner described they are united to a plurality of eonnecting-walls 20, which walls`20 are .continuous in their length, one'being interposedr between each two'of-the folded strips 15, as clearlyillustrated in Figs. 1

erring now in detail to the accompanyand 2. ,When so arranged the side edges of the parallel portions of the strips 15 are connected to the upper and lower edges of the'walls 20, thus completing an enyelop for each of lthe sprin .with a single ply of material at each side of the envelop. The springs are .thereby. prevented from contacting with each other, and they may move independently without such Contact.. and

likewise without the metallic sound that.

emanates from therubbing action of their coils upon each other.

` It is to be observed that access may be` readily had tov each individual pocket for `inserting the springs into and removing the saine therefrom. This is due tothe fact that I while the division walls are connected at their top and bottom marginal portions, the

intermediate edges are not connected, and this provides for free access to the." interior of the several pockets. Thus each individual spring may be readily placed in the pocket whichfit is designed to occupy and remain lsecurely therein without the employment of l tures, and division walls arranged between said unita-ry spring structures and connected to the latter to hold the structures in assembled relation.

2. it. spring construction of the class described, comprising a plurality of unitary spring structures having partitions arranged transversely thereof to divide the structures into a plurality of pockets, a spring arranged in each of said pockets, rand division walls arranged between said unitary structures and connected to the latter to hold the structures in assembled relation.

3. A spring construction of the class described, comprising a plurality of unitary structures each of which has its top and bottom substantially parallel, partitions an ranged transversely of each of said struc\ tures andv having their ends connected to the top and bottom thereof, whereby to divide the structure into a plurality ot pockets, a spring arranged in each of said pockets, and

division walls arranged between said unitary structures and connected to the latter to hold the structures in assembled relation.

t.. l spring construction of the .class described, comprising a plurality of unitary spring structures each of which has itsv top and bottom substantially parallel, a plurality of partitions arranged' transversely of each of said structures and having their ends connected to the top and bottoni thereof, whereby to divide the structure into a plurality of pockets, a spring arranged in each of said poclrets, and division walls arranged between said unitary structures, the edges of said walls being connected to the edges of the tops and bottbms of the unitary struc tures to hold the latter in assembled relation.

5. A spring construction of the class described, comprising a plurality of unitary spring structures each of which has its top and bottom substantially parallel, a plu-- rality of partitions arranged transversely of each structure and having their ends connectl ed to the top and bottom thereof, whereby to divide the structure into a plurality of pockets, a coil spring loosely mounted in yeach of '60 said pockets, the springs of each structure rality of transversely arranged partitions to divide the same into a plurality of pockets, a spring arranged in each of said pockets, and division walls arranged between the longitudinal edges of said spring structures and connected to said edges to hold the structures in assembled relation.

Z spring construction of the class described, comprising a plurality of units each ofwhich is formed of a strip of fabric fold ed upon itself and having its ends connected, a plurality of partitions arranged between the parallel portions of said strip to divide the unit into a series of pockets@ spring arranged in each of said pockets, and division walls arranged betweensai'd units and connected to the latter to hold the several units in assembled relation. y
